Dear Community,While using Wireshark for checking VPLS control packets, I noticed that the format of encoding PW label in LDP-VPLS is different than BGP-VPLS.In LDP-VPLS, as shown below, a label mapping message is transferred between PEs targeted ses...
Dear Community,According to RFC3036: If it is known that a packet must traverse a particular egress
router, and there is an LSP which has an Address Prefix FEC
element which is an address of that router, then the packet is
mapped to that LSP. ...
Dear community,According to RFC2328 (OSPFv2) part 12.1.1 "When an LSA’s age first reaches MaxAge, it is reflooded." then in part 14 it also says that: "As a router ages its link state database, an LSA’s LS age may reach MaxAge. At this time, the rout...

Dear Community,According to rfc2328(OSPFv2), broadcast network is "Networks supporting many (more than two) attached routers,together with the capability to address a single physical message to all of the attached routers (broadcast)". In the definit...
Hello @Harold Ritter ,Thank you for your replies. This is an old version of IPInfusion OcNOS. I checked their latest version and it is now compatible with other vendors (Now the label is encoded in high-order 20 bits).I'm still wondering whether thi...
Dear @MHM Cisco World ,Thanks. Do you know if there was also a behavior change for VPLS label encoding?It seems that there was a similar problem with EVPN ESI encoding but there is still two differences between VPLS label encoding and EVPN ESI encod...
Hi @Harold Ritter ,No. CEs can't ping each other.FAT is not configured on PEs and there are just 2 labels in data-plane packets. 24324 is tunnel label and 389123 is the VPLS label. To be sure, I checked the last link in the provider network (after P...
Hi @Harold Ritter ,This is a data plane packet captured in the provider network:As you can see, the outer label is 389123 which is label-base (389121) + VE-ID (3) - 1, while the other PE expects to receive 24322.Best Regards.
Dear @Harold Ritter ,Yes, Wireshark interprets it correctly (It's maybe based on Cisco implementation), but here is the problem:PE1 shows local label base as 24320 which is correct (4 lowest bits are not considered as a part of label) but the other P...
